Abstract
The invention discloses a cleaning method of a shock tunnel gun barrel. The cleaning method comprises the following steps of: 1) putting a polyurethane foam with an appropriate length into the section of the gun barrel to be washed, wherein the diameter of the polyurethane foam is slightly greater than that of the gun barrel; 2) highly pressurizing to fracture membranes so that the polyurethane foam moves at a high speed in the barrel driven by high pressure gas, thus cleaning the wall of the barrel. By adopting the cleaning method disclosed by the invention, high pressure gas with sufficient pressure is supplied by highly pressurizing to facture the membranes, so as to drive the polyurethane foam to move at a high speed in the gun barrel, and realize mutual friction between the foam and the wall of the barrel rub, thus achieving the effect of cleaning the wall of the barrel.
Description
Technical field
The present invention relates to a kind of cleaning method of shock tunnel gun tube.
Background technology
Shock tube is through after repeatedly detonation is tested, and the gun tube inwall has a lot of carbon distributions and dirt, thereby influences experiment effect.And how effectively to clean the big gun wall is a difficult problem that perplexs shock tunnel experimental work person all the time.
Cleaning gun tube method commonly used has two kinds: the one, utilize cloth wheel two ends bolt rope, and people or mechanical device pull repeatedly at the gun tube two ends to reach and clean big gun wall purpose.This method working strength is big, and cleaning performance is unsatisfactory.The 2nd, the metallic brush polishing gun tube inwall of the dredging machine head that utilization is transformed.This method has damage to tube wall, and the time that polishing is cleaned is longer, and effect is also undesirable.
Summary of the invention
To the problem that prior art exists, the object of the present invention is to provide a kind of cleaning method of shock tunnel gun tube, can clean the gun tube inwall apace, and cleaning performance is fine.
The method that a kind of shock tunnel gun tube of the present invention cleans comprises the steps:
1) in the section to be cleaned of gun tube, put into a polyurethane foam with suitable length, the somewhat larger in diameter of said polyurethane foam is in the internal diameter of said gun tube;
2), make said polyurethane foam high-speed motion in managing under the gases at high pressure promotion, thereby tube wall is cleaned through the high pressure rupture of membranes.
Preferably, the length of said polyurethane foam is 0.3 ~ 0.6 meter.
Preferably, the pressure of said gases at high pressure is controlled at 1 ~ 3 atmospheric pressure.
Preferably, said speed controlling is at 50 ~ 100m/s.
Preferably, at the suitable water of the surface infiltration of said polyurethane foam.
Preferably, be provided with a polyurethane foam receiver, offer the perforate in predetermined quantity and aperture on this receiver in the exit of said gun tube.
The present invention utilizes the high pressure rupture of membranes that the gases at high pressure of enough pressure are provided, thereby promotes polyurethane foam high-speed mobile in gun tube, thus foams and tube wall mutually mutual friction reach the effect of cleaning tube wall.
Description of drawings
Fig. 1 implements view for the present invention;
Fig. 2 is the effect photo of the gun tube inwall after cleaning.
The specific embodiment
As shown in Figure 1, the present invention is employed in the section to be cleaned of gun tube 1 to put into a polyurethane foam 2 with suitable length, and at the suitable water of the surface infiltration of polyurethane foam 2, the somewhat larger in diameter of polyurethane foam 2 is in the internal diameter of gun tube 1.Through the high pressure rupture of membranes, make polyurethane foam 2 promote lower edge arrow A high-speed motion in pipe, thereby tube wall is cleaned at gases at high pressure.In embodiments of the present invention, the length of polyurethane foam 2 is 0.3 ~ 0.6 meter.Owing to have frictional force between polyurethane foam 2 and the tube wall; Receive when gases at high pressure promote and slightly to be out of shape expansion; Therefore adopt somewhat larger in diameter can under lower gases at high pressure, just can reach good fltting speed at 0.3 ~ 0.6 meter polyurethane foam 2, thereby carry out the cleaning of tube wall in gun tube 1 internal diameter and length.
Like this, the pressure of gases at high pressure can be controlled at 1 ~ 3 atmospheric pressure.In addition; The speed of polyurethane foam 2 preferably is controlled at 50 ~ 100m/s; Because under this speed; Polyurethane foam 2 can produce higher temperature with pipe friction on the one hand, so that carbon deposit in the tube wall of gun tube 1 and Fouling Cleaning is clean, also can not produce high temperature on the other hand polyurethane foam 2 is burnt out because speed is too fast.
In addition, as shown in Figure 1, be provided with a polyurethane foam receiver 3 in the exit of gun tube 1, this receiver 3 is cylinders 3 that one one end communicates with gun tube 1, on the barrel of cylinder 3, offers the perforate 4 in predetermined quantity and aperture.Like this, through the quantity and the aperture of perforate 4, can control the fltting speed of polyurethane foam 2 in gun tube 1.
Blow residue off with pressure-air at last, gun tube is dried up with air blast and heater.Fig. 2 is the effect photo of gun tube 1 inwall after cleaning.As shown in Figure 2, behind pressure-air promotion foams cleaning gun tube 2 ~ 3 times, the gun tube inwall carbon distribution and the dirt overwhelming majority are eliminated, and it is obviously better that this method is wiped gun tube method cleaning performance than above-mentioned tradition; Owing to have a small amount of polyurethane particles to remain in above the tube wall after the high-speed friction of foams and tube wall, can wash out through pressure-air again.
The present invention promotes foams with pressure-air (2 atmospheric pressure of only having an appointment in fact), and energy is big, speed is fast, air cleaning and safety.In addition, if receiver 3 just can be realized the control of speed and recycle polyurethane foam 2 that foams are with after clean and can repeatedly use, so wiping big gun cost is lower.
